Structural organization of the RGS9-1 and RGS9-2 proteins. Both RGS9-1 and RGS9-2 proteins contain an N-terminal disheveled, EGL10, pleckstrin homology (DEP) domain, a G-protein γ-subunit-like (GGL) domain and the regulator of G-protein signaling (RGS) domain. RGS9-2 contains an additional C-terminal phosphodiesterase-γ-like domain. RGS9-1 is abundant in the retina, whereas RGS9-2 is highly expressed in the striatum. Abbreviations: aa, amino acids.
